1 Overview
F5-4511V Series F4-516 converter gives the interface
conversion between V.35/10Base-T and G.703 E1. This device
have high performance and low price which is produced by BEI
JING FIBRIDGE Co.,Ltd. F4-516 converter can give not only
interface conversion between V.35 and G.703 E1 but also
interface conversion between 10Base-T and G.703 E1, in
addition F4-516 converter can also make 10Base-T and V.35
together and transmit used E1 channel. Its E1 data interface
also provides an economical digital access solution for E1 and
Fractional E1 network Services, which can work at data rates of
64Kbps to 2048Kbps. Timeslot assignment is accomplished
according to the Data Port speed and manual setting of DIP
switches. The main E1 link may be clocked from the recovered
receive clock, from the Data Port clock, or from an internal
oscillator. For easy to check the fault of network line, the device
provides loop selection, both local loop and remote loop.F4-516
is widely used in communication network, both in WAN and
LAN field.

Notice:
a)
Set TS0 to TS31 all to ON or OFF, the converter will work
under unframed mode, and E1 speed is 2048Kbps. If you
set TS0 to TS31 all to OFF, all 32 timeslots are used to
transmit Ethernet signal; if you set TS0 to TS31 all to ON,
all 32 timeslots are used to transmit V.35 signal.
b)
If the TS0 is set to OFF, then timeslots “ON” carry V.35
signal while timeslots “OFF” carry transmit Ethernet signal.
c)
Under framed PCM30 mode, TS16 of E1 channel is used
to carry command instead of payload. So, at most up to 30
time-slots are available, and the bandwidth is 1920Kbps.
d)
Timeslots can be chosen continuously or discontinuously.
-13-
F4-516 Converter User Manual V1.0
For example, if you want to use 5 timeslots, you could set
TS1-TS5 to ON and set TS6-TS31 to OFF as table. And
also, you could set 5 random timeslots to ON.

In the above application, it is recommended that user select
F4-516 device’s timing signal as unique timing source, and all
the other equipment follow this timing source. F4-516 should be
used in pairs.
7 Diagnosis and Maintenance
Please install and operate equipments according to the
instruction we provided. Equipments maybe damaged for
improper installation and operation.
7.1 Step of installing
a)
Prepare the tools that installation need.
□ Electric iron, which is used to weld the BNC connectors
to E1 cable.
□ E1 analyzer, which is used to test the E1 transmission
line.
b)
c)
□ V.35 tester, to test the V.35 transmission line.
Check the device and accessories according to Packing
List when open the box. If something missing or damaged,
please contact us immediately.
When making E1 cables, if you want to use the 75 ohm
interface of E1 channel, please take out the BNC interface
and fix it on E1 coaxial cable. If you want to use 120 ohm
interface of E1 channel, please fix RJ45 connector on
twisted-pair cable. The sequence of the pins is according to
3.1 of this manual. Notice the distinction of TX line and RX
line.
-15-
F4-516 Converter User Manual V1.0
d)
e)
f)
g)
Place the equipment on neat table or the other platform.
Set dip switches according to your demand. We suggest
when setting timing mode, make sure there is only one
master clock in the channel. Connect the V.35 cable,
10Base-T cable and E1 cables to the interfaces. Please
reference the Notice ②.
Make sure power switch is off. Connect power line to
device, then turn on the power switch.
If the equipment works normally, all LED indicators are off
except for PWR. When you connect equipments to
Ethernet, the indicator LINK/ACK is on or blink and the
indicator FDX is on, which means Ethernet is working at
Full Duplex mode. If there is something wrong, please refer
to ‘8 Fault and Solution’.
Notice：
①
Make sure the type of power supply is in accordance with
the equipment request.
②
For preventing equipment from damage, we suggest
mightily you connect or disconnect V.35 cable with power
off.
③ It is very important that equipments are connected to earth
rightly and firmly. Check the distributing of the power
supply and the connection to the earth.

Bit error test online
F4-516 provides a useful function, bit error test online, to
diagnose device and transmission line, with loop back test
functionality. And the PTOK led shows the test result.

Step:
a) Set converter A to remote loop back (set bit1 of SW1 ON)
or local loop back (set bit3 of SW1 ON ), then LOOP LED
on A should blink (remote loop back ) or be ON (local loop
back ).
b) Set bit5 of SW1 on converter A ON, which means A is
working under Bit Error Testing Online mode. If PTOK led
on A is ON, there is no error bit in the signal. If LOOP led is
OFF, it means there are error bits in the signal. Then, if bit3
of SW1 on A is ON (local loop back), there maybe some
troubles occur in the equipment A. if bit1 of SW1 on
converter A is ON (remote loop back), there maybe some
troubles occur in converter A, or in E1 channel, or in device
B.

F4-516 Converter User Manual V1.0
7.7
Selection of V.35 data and timing phase
F4-516 can examine and adapt to the phase of data received
from V.35 port, without any manual setting. For timing phase,
there is a bit in dip switch to setup it. Generally, equipment can
work well without setting timing phase. Only if converters
cannot synchronize with link partner, or have lot of bit errors,
you should change this setting. You can make it though bit6 in
the table 2.
7.8
Testing interface of Ethernet
Connect Ethernet port and turn on the power switch. If the
connection is all right, some LEDs on the equipment may show
as follow:
□ All red LEDs are OFF.
□ LINK turns ON, which means Ethernet port is linked with
no data receiving or transmitting, or blink, which means
Ethernet port is linked with data receiving and transmitting.
□ If converter is working at Full Duplex mode, FDX turns ON.
You can use PING command to test the Ethernet channel. The
connection is shown as picture below.
